Justin Bieber's dad Jeremy is a proud papa.

Just days after photos leaked online of his pop star son naked while on vacation in Bora Bora, Jeremy tweeted out his approval of his son's 'thing,' Gawker reported. Jeremy's awkward dad joke elicited responses from grossed-out fans on social media.

"@justinbieber what do you feed that thing. #proud daddy," the 40-year-old father of three wrote on Twitter, adding a blushing smiley face emoji at the end.

The comment seems to be in response to the nude photos of his son that showed him completely in the buff. The photos were taken by paparazzi during Bieber's Bora Bora vacation with rumored girlfriend Jayde Pierce, as previously reported by HNGN.

Bieber's team reportedly responded to the photos of the well-endowed Canadian pop star with a cease and desist letter sent to the New York Daily News, as previously reported by HNGN. The letter reportedly stated that the outlet had 12 hours to remove the photos, but the Daily News has yet to comply.

Meanwhile, fans expressed shock and disgust at the seemingly "creepy" way Jeremy responded to his son's naked photos by posting memes of various celebrities making scrunched or confused faces.

Jeremy doesn't have the best reputation, according to Gawker. In the past, Jeremy's been accused harassment stemming from a 2014 incident with a flight attendant and another incident later that year where he allegedly trashed an apartment that his son paid for.
